Be it known that 1,

Emperor, and residing in the town of Bath, near Dusseldorf, Kingdom of Prussia, and German Empire, have invented a certain new and useful Fire-Extinguishing Apparates with Siphon Arrangement, of which the following is a specification.

This invention has reference to an an rangement in connection -with fire extinguishing apparatuses, by 1D8213lS 0f which 1t 'becomes possible to sprinkle vertically downward with the apparatus, without any possibility of the escape of the gases under pressure whi ch serve forthe operation of the apparatus. 1 I

With the well-known fire-extinguishing apparatuses it was only possible to sprinkle downward in an inclined direction, but not vertically downward, in View of; the eutrance opening of the interior raising pipe for the liquid, emerging from the. latter, when the nozzle was directed downward, so that the gases were free. to escape.

The new purpose of being able to sprinkle with the hand operated ire extinguishing apparatus both in an upward direction as well as in a downward direction without allowing the gases to escape, and until the apparatus has been completely emptied by the sprinkling, ing a siphon in the interior of the fire ox.- tiuguishing apparatus, one branch of the said siphon communicating with the interior ol the exit pipe, while the other leg of the siphon conununicates with the receptacle for the liquid. The length of this siphon is almost equal to that of the raising pipe and it is arranged opposite the handle of the apparatus in the same manner as the raising pipe. by which means the effect is produced of keeping the siphon always below the level of the water, so that it is prevented from running empty. For thepur pose of accomplishing the objectreferred lo, the, arrangement of the long siphon is combined with the fact of imparting anarrow sectional area to the issue opening of the nozzle as compared with the sectional area of the exit pipe.

Y Upon the drawing two forms of construction for carrying out the invention are illus-.

trated.

In the form of construction according to Specification of Letters Patent.

laterally arranged exit pipe at another U- shaped piper, in such a manner, that, as above referred to, one end of said pipe. opens out into the interior of the liquid container 7', while the other end 6 terminates in the mterior oi the pipe a.

The mode of operation of the device is as follows :-If it is desired to sprinkle with the apparatus in a downward direction water will flow through the siphon tube and form the liquid container into the pipe 0: upon the descent of the water level in the pipe at in consequence of the escape of the extinguishing liquid from the sprinkling opening a of the apparatus, until the Water levels in f and in a are at the same height. Thus the contents of water of the apparatus flows through the siphon tube 0 and into the pipe (1. The water levels in f and in a arekept at approximately the same level on account.

of the narrow sectional area of the escape opening of the nozzle. \Vhen it is desired to sprinkle, with the apparatus afterward in an upward'direction, the apparatus is reversed, so thatits nozzle is directed upward, and the Water will then enter into the pipe a through the entrance opening 5.

In the form of construction according to Fig. 3, the exit pipe a is surrounded by another pipe 71, the opening of which i is arranged in'the proximity of the sprinkling nozzle.

of operation is the same in this case as in the form of construction in accordancewith Fig. 1. V

What I claim and desire to secure by Letters Patent of the United States i's 1. A hand operated fire extinguisher actuated by fluid pressure, comprising a liquid container or any shape, anexitpipe extending almost in full length from the outlet nozzle along the side of the container, a siphon either limb of which is approximately equal to the length of the exit pipe the discharge limb of the siphon being inclosed throughout its length within said exit pipe, and the cross sectional area of the internal diameter of the discharge nozzle, being less than that of the exit tially as described.

The 'Ushaped siphon tube is has' bccnintroduced into the pipe 71-. The mode Figures 1 and 2, there is provided upon the pipe, substan- 2. A hand operated fire extinguisher actuated by fluid pressure, comprising a liquidcontainer of any shape, an exit pipe exi tending almost in full length from the outlet nozzle along the side of the container, 21 covering pipe surrounding the exit pipe being 5 closed at the open end of the exit pipe and 1 open at the opposite end near the outlet noz- 3 211e, a. siphon either limb of which is 'approxi- 1 lately equal to the length of the covering pipe, the discharge limb of the siphon being inclosed throughoutits length Within said 10 covering pipe, and the cross section-ll area I of the internal diameter of the discharge nozzle being less than that of the exit pipe substantially as described.
